windows nt compatibility

The tag covers discussions about compatibility with the Windows NT architecture, including efforts to run Windows software on alternative NT-compatible systems. A key example is ReactOS, an open-source reimplementation of Windows NT, which has demonstrated the ability to run games like Half-Life on real hardware using its own kernel, driver stack, and Win32 implementation. This shows progress in NT compatibility beyond Microsoft's own operating systems, highlighting how clean-room NT clones can handle real-time workloads and OpenGL graphics. The tag focuses on technical milestones in achieving NT-level compatibility for Windows applications.
